aerotactic การใช้

• Two different magneto-aerotactic mechanisms  known as polar and axial  are found in different MTB strains.
• The magnetic field provides both an axis and a direction of motility for polar magneto-aerotactic bacteria, whereas it only provides an axis of motility for axial types of bacteria.
• Some strains that swim persistently in one direction along the magnetic field ( either north-seeking [ NS ] or south-seeking [ SS ] )  mainly the magnetotactic cocci  are polar magneto-aerotactic.
• Those MTB that swim in either direction along magnetic field lines with frequent, spontaneous reversals of swimming direction without turning around  for example, freshwater spirilla  are axial magneto-aerotactic and the distinction between NS and SS does not apply to these bacteria.
